I am quite new in pentesting and looking for a method of privilege elevation for PosqtreSQL server’s system user (nt authority/network service). Database server is deployed on Windows (version 10.0.19045.4291). The matter is that network service can’t view user’s home directories and it is very important for me. I’d like to know if it’s possible

I’ve tried some exploits, but win defender deletes them right away. Any help is greatly appreciated. I have access to database via sql injections. All i can use now is COPY ... FROM PROGRAM '???'
